SD42525_Datasheet 32V/1A, HIGH-EFFICIENCY HYSTERESIS LED DRIVER WITH BUILT-IN MOSFET DESCRIPTION SD42525 is a step-down constant current converter with inductance current continuous-conduction mode, it is used for driving LED or LEDs in series. The output current is adjustable which is up to 1A in 6~32V input voltage range. LED whose power is tens of watts can be driven by SD42525 with different input voltages and peripheral elements. With built-in power switch, average current of LED can be set through external high-side current sensing. Analog dimming and wide range PWM dimming are available through pin DIM and soft-start time can be set by capacitor value which is connected between pin DIM and ground. It adopts two patent technologies: output current pensation when input voltage varies and current limiting through maximum duty factor when difference between input/output APPLICATIONS voltages is small. For SD42525, package of SOP-8-225, SOT-23-6L and SOT89-5L (no dimming) are available. - Low-voltage LED spotlight, replacing Halogen lamp - Car-mounted LED lamp Features - LED backup lamp - LED signal lamp - Few peripheral elements - Built-in 36V power MOSFET - Wide input voltage range: 6V~32V - Maximum 1A output current - Excellent output current accuracy: ±3% - Multiplex pin DIM is used for chip switch, analog dimming and PWM dimming. - Soft start function - LED open/short-circuit protection - High efficiency up to 96% - Output constant current which is adjustable ORDERING INFORMATION Part No. SD42525 SD42525TR SD42525ETR SD42525KTR Package SOP-8-225-1.27 SOP-8-225-1.27 SOT-89-5L SOT-23-6L Marking SD42525 SD42525 525E 525K Material Pb free Pb free Pb free Pb free Packing...
